COLLAPSIBLE WINDOW CHAIR.

Application filed December 22, 1923.

To all whom it may concern. v

Be it known that I, MICHAELIS Scion- MANN, a citizen of the UnitedStates, and a resident of New York, borough of Bronx, in the county ofBronx and State of New York, have invented certain new and usefulImprovements in a Collapsible Window Chair, of which the following is afull, clear, and exact specification.

This invention relates more particularly to a class of devices adaptedto be used for supporting persons on the exterior of winows.

My invention has for its object primarily to provide a device designedto be employed to support persons on the exterior of the windows ofbuildings and other structures for accomplishing without the danger offalling various kinds of work, such as cleaning windows, glazing,painting, hanging and taking down awnings and for other general uses,and which is made preferably in the form of a chair serving to overcomethe hesitancy of timid persons against working exteriorly of windows,The chair is further adapted to be collapsed and removed from the windowfor occupying a limited space when not in use. The invention consists essentially of a seat or platform for being dis posed outwardly of awindow upon the sill of its frame for accommodating a person thereoneither in a sitting or standing posture on the exterior of the window,and serving to prevent the occupant from liability of falling from theseat, a back is flexibly connected to the outer part of the seat. Theback may be swung upwardly and clownwardly from the seat so that thedevice may be packed in a limited space when not in use, and means isprovided on the seat for engaging the inner edge of the sill toremovably fasten the seat to the window frame.

A further object of the invention is to provide a window chair of asimple, efficient and durable construction which may be made of suitablematerial in any appropriate size and shape.

With these and other objects in view, the invention will be hereinaftermore full explained with reference to the accompanying drawing forming apart of this specification in which similar characters of referenceindicate corresponding parts in all the views, and will then be ointedout in the claim at the end of the escription.

Serial No. 682,179.

In the drawing, Figure 1 is a fragmentary view showing an innerelevation of a window with one form of my improved collapsible chairapplied thereto.

Fig. 2 is a side elevation of the chair, and

Fig. 3 is a front elevation of the chair showing the seat folded uponthe back of the chair.

The device or chair has a seat or platform 10 which may be of anyappropriate size and shape, though the form of the seat illustrated issubstantially rectangular and of a size to permit of being removablydisposed from the inner to the exterior of the win dow, as 11, of abuilding or other structure so as to lie upon the sill, as 12, betweenthe stiles, as 13, 14:, of the frame of the window as well as protrudinga sufficient distance to allow a person to be accommodated on the seatin a standing or sitting posture exteriorly of the window. The seat isalso preferably adapted to be arranged so that its inner edge will bedisposed on the usual protruding inner edge of the sill 12 of the windowand so that the central part of the seat will be disposed above thelower guide rail, as 15, of the sash 16 of the window.

To the outer edge of the seat or platform 10 may be hinged or flexiblyconnected, at 17, the lower edge of a back, as 18, for serving toprotect a person on the seat against liability of falling, and this backis pref erably substantially rectangular as well as adapted to be swungupwardly and down wardly from the seat toward and from the exterior ofthe window. The chair may thereby be collapsed for occupying a limitedspace when not applied to a window, and the seat and back may be made ofwood, fibre, metal or other suitable material.

In order to limit the upward or outward movement of the back 18 from theseat 10; that is, to prevent the back from moving beyond anapproximately right angular position relative to the seat when swungupwardly, I provide flexible connections, as 19 and 20. The flexibleconnections 19, 20 may be of any suitable formations so that they willfreely yield or bend when the seat and back are folded together, thougheach of these flexible connections shown are in the form of a pair ofchains, as 21, 21 and 22,

chains 21. 21 are held, at 24, to parts of the back 18 in proximity tothe hinge 17. @ne of the ends of the chains 22, 22" of the flexibleconnection 20 is attached, at 25, and 25 to the ends of a bar, as 26,disposed across and below the edge of the seat opposite to the back 18,and the other ends of the chains 22, 22 are fastened, at 27, 27, to theupper parts of the side edges of the back. The back will thereby beheldagainst liability of movement beyond its right angular position whenswung upwardly from the seat for protecting the occupant from danger offalling, and the back also tends to over come the hesitaney of timidpersons against working eXteriorly of windows for cleaning the panes ofglass or glazing or painting or for accomplishing other work.

Under the ends of the inner edge of the seat 10 are correspondinghoolesliaped members or catches 28, 29 adapted to engage the protrudinginner edge of the sill 12 for movably fastening the seat to the frame ofthe window. Under the seat 10 below the back 18 may be similarsubstantially U-shaped members or supports 30, 31 for serving as meansto support the seat 10 at a determined elevation above the outer part ofthe sill of the window frame. The hookshaped member 28' and the U-shapedmember or support 30 may be integrally formed from a metal bar 32 whichis fastened on the underside of one of the side edge parts of the seat.One of the ends of the bar 32 is curved downwardly to provide the hookmember 28, and the other end of the bar is bent to provide the U-shapedsupport 30, while the central part of the bar may be bent to provide, arecess, as 33, for accommodating the cross rail 15 of the sill of thewindow frame. The hook-shaped member 29 and the U-shaped member orsupport 31 may also beintegrally formed from a pliable metal bar 34which is secured on the underside of the other side edge part of theseat. One of the end parts of this bar 34 is curved downwardly toprovide the hook member 29, and the other end part of the bar is bent toprovide the ltsliaped support 31. The central part of the bar 34 bent toprovide a recess, as which is in register with the recess 33 toaccommodate the cross rail 15 of the sill of the window frame. When thechair fastened to the window frame by engaging the inner edge of thesill with the hook-shaped members or catches'28, 29, the seat 10 andback 18 will be disposed outwardly of the window, and the bar v26extends across the free end parts of the hook-shaped members in spacedrela tion to the seat for also engaging the underside of the inner edgeof the sill of the window frame. The fastening means 25, 25 of thechains 22, 22 may be in the forms of bolts or screws for also securingthe bar 26 to the free end parts of the hook-shaped members, and byattaching the chains to the bar and hook-shaped members the pres sure ofthe occupant of the chair against the back will serve to pull the chainsfor causing the hook-shaped members and the cross-bar 26 to tightly gripthe sill of the window frame. Between the seat and the central parts ofthe bars 32 and 34 may be two cross-bars, as 36, 37, for bracing thebars 32 and 34, and the bars 36, 37 may be fastened to the seat 10 byremovable screws or bolts to allow the bars 36, 37 to be suitably spacedfrom each other as occasion may require.

In the foregoing description, I have em bodied the preferred form of myinvention, but I do not wish to be understood as linr iting myselfthereto, as I am aware that modifications may be made therein withoutdeparting from the principle or sacrificing any of the advantages ofthis invention. therefore, I reserve to myself the right to make suchchanges as fairly fall within the scope thereof.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent The combination with a collapsible window chair havinga substantially rectangula r seat with a back hinged thereto, of twospaced parallel. bars fastened on the underside of the seat and bothbars having ou of their corresponding ends bent to provide yieldingdepending hooks for being disposed over the inner edge of the sill ofthe window. said bars having their other ends bent in approximately ti-shapes to provide sup ports for elevatingthe seat above the sill andthe bars having their central parts also bent to provide recesses foraccommodating the rail of the window sill, a cross-bar connecting' thefree ends of the hooks, and chains having their ends attached to upperparts of the back and to the free end parts of the said hooks forlimiting the upward movement of the back and to force the free ends ofthe hooks toward the seatwhen the back is under upward pressure.

This specification signed and witnessed this 21st day of December. A.1923.
